The seat portion 10 is configured to support the buttocks of a child.The backrest portion 20 is configured to support the back of the childand extends upward with a lower end thereof connected to the seatportion 10. In this embodiment, the seat portion 10 and the backrestportion 20 are separate components, which can be foldably connectedtogether by a hinge mechanism. In other embodiments, the seat portion 10and the backrest portion 20 may be integrally formed. The backrestportion 20 has a plurality of adjustment holes 22 formed therein frombottom to top. In this embodiment, six adjustment holes 22 are dividedinto two columns in a horizontal direction, and three adjustment holes22 in each column are equally spaced apart on the backrest portion 20along a vertical direction. In some embodiments, the spacing between theadjustment holes 22 in each column can be unequal. A height of theshoulder strap 40 can be conveniently adjusted by arranging theadjustment holes 22 equally spaced apart. It should be understood that anumber of adjustment holes 22 is not limited hereto, and may be 4, 8, ormore.

As shown in FIG. 3 and FIG. 4, two waist belts 30 (FIG. 1 and FIG. 2)are provided and are configured to encircle the waist of the child fromboth sides. The waist belts 30 may be nylon woven belts. Each waist belt30 includes a first end 32 and a second end 34. The first end 32 isfixed at a corresponding position of the backrest portion 20, and thesecond end 34 is movably connected to the buckle 50.

Two shoulder straps 40 are provided and are configured to secure theshoulders of the child. The material of the shoulder strap 40 is thesame as that of the waist belt 30. In some embodiments, the material ofthe shoulder strap 40 differs from the material of the waist belt 30.The shoulder strap 40 has a fixed end 42 (FIG. 8) and a free end 44. Thefixed end 42 is fixed to a rear side of the backrest portion 20 (seeFIG. 8) by sewing or the like. The free end 44 goes through one of theadjustment holes 22 on the backrest portion 20 and is removablyconnected to the second end 34 of the waist belt 30. As shown in FIG. 3and FIG. 4, in this embodiment, a first shoulder strap buckle 46 isprovided on the free end 44. The first shoulder strap buckle 46 isshaped substantially as a rectangle and includes a rectangular fixingring 462 and a hook portion 464 extending laterally from a short side ofthe fixing ring 462. A gap is formed between the hook portion 464 andthe fixing ring 462. The free end 44 is fixed on the fixing ring 462 bysewing. A fixing hole 342 is formed at the second end 34 of the waistbelt 30 by sewing or the like. The hook portion 464 of the firstshoulder strap buckle 46 can be inserted into the fixing hole 342, so asto connect the shoulder strap 40 and the waist belt 30. The hook portion464 of the first shoulder strap buckle 46 can also be removed from thefixing hole 342, so as to separate the shoulder strap 40 from the waistbelt 30. Referring to FIG. 4, to facilitate insertion and removal of thehook portion 464, a diameter of the fixing hole 342 gradually decreasesalong a direction in which the hook portion 464 is inserted into thefixing hole 342.

The buckle 50 is movably provided on the seat portion 10, and isconfigured to removably fix the left and right waist belts 30 and theshoulder straps 40 together. In this embodiment, a crotch guard 60extending between two thighs of the child is provided on the seatportion 10. The buckle 50 is fixed on the crotch guard 60. The crotchguard 60 can prevent the hard buckle 50 from being in direct contactwith the child, so as to avoid injury to the child. A width of thecrotch guard 60 gradually increases along a direction from a jointbetween the crotch guard 60 and the seat portion 10 to a position atwhich the buckle 50 is located, which is more ergonomic. Specifically,the buckle 50 includes a female buckle 52 and a male buckle 54. Thefemale buckle 52 is fixed on the seat portion 10. One end of the malebuckle 54 forms a loop that is slidably sleeved on the waist belt 30,and the other end of the male buckle 54 forms a tab that is removablybuckled to the female buckle 52. By buckling the male buckle 54 on thewaist belt 30 to the female buckle 52 on the crotch guard 60, theshoulder strap 40, the waist belt 30, and the crotch guard 60 arefastened together to implement connection. The joint restraint of theshoulder strap 40, the waist belt 30 and the crotch guard 60 ensuressitting stability and safety of the child in the child carrier 100.

Referring to FIG. 1 through FIG. 3, the working principles of the childcarrier 100 with the height-adjustable shoulder strap 40 will bedescribed in greater detail.

During normal use, the fixed ends 42 of the two shoulder straps 40 arefixed on the rear side of the backrest portion 20, and the positions atwhich the fixed ends 42 are fixed are higher than the uppermostadjustment holes 22. The free ends 44 of the two shoulder straps 40 gothrough one of the adjustment holes 22 from the rear side of thebackrest portion 20 and then are located on a front side of the backrestportion 20. Each free end 44 is then connected to a corresponding secondend 34 of the waist belt 30 through a corresponding first shoulder strapbuckle 46, thereby connecting the shoulder strap 40 to the waist belt30. The first end 32 of the waist belt 30 is fixed on the backrestportion 20, and the male buckle 54 movably sleeved on a middle of thewaist belt 30 is buckled to the female buckle 52.

When the height of the shoulder strap 40 needs to be adjusted, the hookportion 464 of the first shoulder strap buckle 46 can be taken out fromthe fixing hole 342, so as to separate the free end 44 of the shoulderstrap 40 from the second end 34 of the waist belt 30. Subsequently, thefree end 44 of the shoulder strap 40 goes through the current adjustmenthole 22 and returns to the rear side of the backrest portion 20. Then, asuitable adjustment hole 22 is selected, and the free end 44 goesthrough the selected adjustment hole 22 and is then connected to thesecond end 34 of the waist belt 30 through the first shoulder strapbuckle 46, so as to connect the shoulder strap 40 and the waist belt 30.

Compared with the related art, since the plurality of adjustment holes22 are provided on the backrest portion 20 of the child carrier 100 frombottom to top, the free end 44 of the shoulder strap 40 can selectivelygo through the adjustment holes 22 at different heights and is connectedto the waist belt 30. Since the heights of the adjustment holes 22 aredifferent, the configurations of the shoulder strap 40 can be adjustedaccording to the height and body shape of a child, thereby improvingsitting comfort and safety of the child.

Referring to FIG. 5 through FIG. 7, a child carrier 200 according to asecond embodiment is similar to that of the child carrier 100 of thefirst embodiment. A difference lies in that a second shoulder strapbuckle 36 is provided on the waist belt 30, and the free end 44 of theshoulder strap 40 is removably connected to the second shoulder strapbuckle 36.

As shown in FIG. 6 and FIG. 7, a fixing hole 442 is formed on the freeend 44 of the shoulder strap 40 by sewing or the like. The secondshoulder strap buckle 36 includes a main body portion 362 that is shapedsubstantially as a rectangle, and a hook portion 364 extending laterallyfrom a short side of the main body portion 362. Two elongated holes areprovided on the main body portion 362, the second end 34 of the waistbelt 30 can go in through one hole and go out through the other hole,such that a position of the second shoulder strap buckle 36 on the waistbelt 30 can be conveniently adjusted. A gap is formed between the hookportion 364 and the main body portion 362, such that the hook portion364 can be removably engaged with the fixing hole 442. Referring to FIG.7, to facilitate insertion and removal of the hook portion 364, adiameter of the fixing hole 442 gradually decreases along a direction inwhich the hook portion 364 is inserted into the fixing hole 442.

A usage method of the child carrier 200 according to the secondembodiment is similar to that of the child carrier 100 of the firstembodiment. The free end 44 of the shoulder strap 40 can selectively gothrough adjustment holes 22 at different heights, and is connected tothe waist belt 30, thereby improving sitting comfort and safety of thechild. It should be noted that, because the second shoulder strap buckle36 is slidably disposed on the waist belt 30, when the shoulder strap 40goes through the adjustment hole 22 at a lower position, a user can pullthe second end 34 of the waist belt 30 to cause the second shoulderstrap buckle 36 to move on the waist belt 30 toward the buckle 50, so asto ensure that a length of the waist belt 30 from the adjustment hole 22to the buckle 50 is not too long, thus avoiding tangling with otherstraps subject to playing with by the child. That is, the lengths of thewaist belt 30 and the shoulder strap 40 bound to the child aretightened, which can meet restraint requirements and ensure sittingsafety of the child.

Referring to FIG. 9, the structure of a child carrier 300 according to athird embodiment is similar to that of the child carrier 100 of thefirst embodiment. A difference lies in that the fixed end 42 of theshoulder strap 40 of the child carrier 100 is fixed on the rear side ofthe backrest portion 20 as shown in FIG. 8, however the fixed end 42 ofthe shoulder strap 40 of the child carrier 300 is adjustably connectedto the rear side of the backrest portion 20 through a third shoulderstrap buckle 70 as shown in FIG. 9.

The third shoulder strap buckle 70 is fixed on the rear side of thebackrest portion 20 through a short strap. The third shoulder strapbuckle 70 is shaped substantially as that of the main body portion 362of the second shoulder strap buckle 36. Two elongated holes are providedon the third shoulder strap buckle 70. The fixed end 42 of the shoulderstrap 40 can go in through one hole and go out through the other hole,such that a position of the third shoulder strap buckle 70 on theshoulder strap 40 can be conveniently adjusted.

Since the third shoulder strap buckle 70 is slidably disposed on theshoulder strap 40, when the shoulder strap 40 goes through theadjustment hole 22 at a higher position, the user can pull the fixed end42 of the shoulder strap 40 to cause the extra shoulder strap 40 to gothrough the third shoulder strap buckle 70, so as to ensure that alength of the shoulder strap 40 from the adjustment hole 22 to thebuckle 50 is not too long. That is, the length of the shoulder strap 40bound to the child is tightened, which can meet restraint requirementsand ensure sitting safety of the child.
